Mercedes-Benz has provided Jay Leno with a 6.2-liter V8 (M156) to put into his vintage 300SEL 6.3.

the M156 uses a traditional wet-sump setup, as opposed to the SLS’ M159, with its dry-sump lubrication system, bespoke internals and magnesium intake manifold. The M156 is used in many Mercedes-Benz AMG models, such as the S63, SL63 and E63 AMG. It’s only down 45 bhp from its gullwing sibling, putting out 518 hp rather than the SLS’ 563 hp
